Simultaneous pancreas-kidney (SPK) transplantation is considered medically necessary when BOTH of the following criteria are met:

SPK medical necessity: 1) Medical necessity for kidney transplantation is met; AND 2) Either diabetes mellitus (if individual is ≥18 years old must be on insulin) OR pancreatic exocrine insufficiency.see node text

From policy 'SPK' criteria.

inv-03: Pancreas Transplantation (PTA and PAK) — ONE of the following is met

Pancreas transplantation is considered medically necessary when ONE of the following is met:

Pancreas transplant medical necessity: Diabetes mellitus (if individual is ≥18 years old must be on insulin); pancreatic exocrine insufficiency; or requires procurement/transplantation of a pancreas as part of a multiple organ transplant for technical reasons. (PAK is considered medically necessary when pancreas transplantation criteria are met.)see node text

Includes PTA and PAK per policy.

inv-04: Procedure medical necessity — Covered when ALL applicable policy clinical criteria are met and candidate is not contraindicated

Covered when ALL applicable policy clinical criteria are met and transplant candidate is not contraindicated per center or policy guidance.

Procedure coverage condition: The listed transplant procedure or procurement code is considered medically necessary only when the applicable clinical policy criteria are satisfied and the transplant candidate does not have contraindications per this policy or transplant center criteria.

Applies to CPT/HCPCS/S codes listed in policy; see documentation and prior authorization requirements.

inv-05: Waiting time and referral criteria — UNOS/OPTN and KDIGO guidance

Waiting time and registration eligibility per UNOS/OPTN and KDIGO guidance.

Adult kidney waiting time accrual: For candidates ≥18 years, waiting time is based on the earliest of: registration date with GFR or measured/estimated CrCl ≤20 mL/min; the date after registration when GFR/CrCl becomes ≤20 mL/min; or the date the candidate began regularly administered dialysis.GFR/CrCl <=20 mL/min

UNOS/OPTN Policy 8.3.A.

Kidney-pancreas waiting time for adults: To accrue kidney‑pancreas waiting time for candidates ≥18 years: be registered for kidney‑pancreas, qualify for kidney waiting time per Policy 8.3, AND be on insulin.on insulin

UNOS/OPTN Policy 11.3.B.

KDIGO transplant planning threshold: Consider planning for preemptive kidney transplantation when GFR is <15–20 mL/min/1.73m2 or the 2‑year kidney failure risk is >40%.

inv-06: Contraindications — Contraindications that render transplantation not appropriate

Contraindications that render transplantation not appropriate.

Absolute contraindications (general): Active infections; active malignancy (excluding non-melanoma skin cancers); active substance use disorder; reversible kidney failure; uncontrolled psychiatric disease; documented active and ongoing treatment nonadherence; significantly shortened life expectancy.

Recipient age alone is not a contraindication for kidney transplant per policy.

Absolute contraindications for SPK/PAK (most centers): Age >65 years; non‑insulin‑requiring diabetes; BMI >35 kg/m2; advanced cardiopulmonary disease (EF <30% or PASP >50 mmHg or uncorrectable CAD on stress testing); heavy smoking; severe peripheral vascular disease; moderate‑to‑severe dysfunction in other organs (lung, liver, CNS); active malignancy (except nonmelanoma skin cancer or low‑grade prostate cancer); severe infection; inadequate psychosocial support or financial resources; active substance addiction or abuse; major unmanaged psychiatric illness; poor functional/performance status (frailty, severe deconditioning, wheelchair dependence, need for chronic oxygen); chronic nonhealing wounds; projected life expectancy <5 years.

Center‑specific variation may apply; many centers adopt these criteria.

Living donor partial or segmental pancreas transplantation (living donor pancreas transplantation) is considered experimental, investigational, or unproven. This policy position applies to segmental or partial pancreas procedures performed using a living donor and reflects the current coverage exclusion for these techniques.

Use of the unlisted pancreas procedure code 48999 to report living donor partial/segmental pancreas transplantation is considered Experimental/Investigational/Unproven and is not a covered billing route for living donor pancreas transplantation.

The policy statement regarding Mechanical preservation machines has been removed from this coverage policy. Donor organ procurement and transport, including mechanical preservation services, are now addressed under Cigna Omnibus Reimbursement Policy R24.

Kidney, pancreas, or pancreas‑kidney transplantation is considered not medically necessary when any of the policy’s listed contraindications are present. Examples include active infections, active malignancy expected to limit survival, persistent or recurrent major systemic infections, demonstrated patient noncompliance that jeopardizes graft survival, and other absolute or center‑adopted contraindications listed in the policy.

Transplantation is not medically necessary when absolute contraindications are present. Representative examples include active infection, active malignancy (excluding non‑melanoma skin cancer in some circumstances), active substance use disorder, inadequate psychosocial support or financial resources, projected life expectancy <5 years, and other conditions listed in the policy that would substantially impair transplant success.

Candidate Criteria

inv-39: Candidate Criteria — eligibility rules by transplant type

Candidate eligibility rules by transplant type.

Kidney candidate: Adults with GFR or creatinine clearance ≤20 mL/min/1.73m2; pediatrics with stage 4 CKD (eGFR <30 mL/min/1.73m2); or end‑stage renal disease on regular dialysis.

SPK candidate: Must meet kidney transplant medical necessity criteria AND have diabetes mellitus (if ≥18 years must be on insulin) OR pancreatic exocrine insufficiency.

Pancreas candidate (PTA/PAK): Diabetes mellitus (if ≥18 years must be on insulin); pancreatic exocrine insufficiency; or require pancreas procurement/transplant as part of a multiple organ transplant for technical reasons. (PAK: pancreas transplant criteria must be met.)

inv-40: Candidate listing and timing — UNOS/OPTN and KDIGO relevant to listing and timing

Contraindications

Contraindications that generally render kidney and/or pancreas transplantation inappropriate include active infections, active malignancy (excluding non‑melanoma skin cancers), active substance use disorder, reversible kidney failure, uncontrolled psychiatric disease, and documented active and ongoing treatment nonadherence. A significantly shortened life expectancy is also generally considered a contraindication.

Additional or transplant‑specific contraindications commonly adopted by centers for simultaneous pancreas‑kidney (SPK) or pancreas‑after‑kidney (PAK) transplantation include factors such as Age >65 years, non‑insulin‑requiring diabetes, and BMI >35 kg/m2, as well as advanced cardiopulmonary disease, heavy smoking, severe peripheral vascular disease, inadequate psychosocial support, and other organ dysfunction listed in the policy.

The policy’s full contraindication listing reiterates that absolute contraindications include active infections, active malignancy (excluding non‑melanoma skin cancers), active substance use disorder, reversible kidney failure, uncontrolled psychiatric disease, and documented active nonadherence. For pancreas‑related transplants, additional absolute contraindications (e.g., advanced cardiopulmonary disease, severe peripheral vascular disease, chronic nonhealing wounds) are specified and may preclude coverage.

Submit requests with covered diagnosis and procedure codes current as of the date of service.
Claims lacking covered codes or appropriate documentation will be denied.

Documentation Required

Required Clinical Documentation

Providers must include specific clinical and operational documentation to support medical necessity for kidney, pancreas, or combined transplants. Documentation should be consistent with applicable guidelines and literature cited in this policy.

Evaluation Requirements

Documentation Required

Use race‑neutral eGFR calculations per OPTN and NKF/ASN

Transplant centers are required to use race‑neutral calculations when estimating GFR for purposes covered by OPTN policy; the policy references OPTN and NKF/ASN recommendations to implement race‑neutral eGFR reporting.

Effective July 27, 2022, OPTN requires use of race‑neutral calculations for estimating GFR for transplant candidate purposes.
NKF/ASN recommended implementation of the 2021 CKD‑EPI equation without race.

Note

Follow OPTN/UNOS evaluation and registration rules

Additional evaluation requirements and operational details for candidate assessment (e.g., waiting time accrual rules and pancreas registration requirements) are specified in OPTN/UNOS policies referenced by this document.

UNOS/OPTN Policy 8.3.A defines adult kidney waiting time accrual criteria.
OPTN Policy 11.2.A lists pancreas registration requirements.

Center Requirements

Note

Center requirements referenced; specific accreditation language not specified

Transplant center‑specific requirements and OPTN policy influences are referenced; explicit accreditation requirements (e.g., FACT) are not specified in this policy fragment.

Centers should follow OPTN/UNOS policies and any center‑specific selection criteria when documenting eligibility.

Background

Kidney failure (Stage 5 CKD/ESKD) is defined in the policy as an eGFR <15 mL/min/1.73 m2 for ≥3 months or the need for dialysis. Treatment options include dialysis or kidney transplantation; transplant consideration thresholds referenced in the policy include adult candidates with measured or calculated creatinine clearance or GFR ≤20 mL/min/1.73 m2 and pediatric candidates with stage 4 CKD (eGFR <30 mL/min/1.73 m2).

Definitions

inv-34: Kidney failure / Stage 5 CKD (ESKD) definition — eGFR <15 mL/min/1.73m2 for 3 months or on dialysis

ESKD / Stage 5 CKD definitionKidney failure (Stage 5 CKD/ESKD) = estimated glomerular filtration rate (eGFR) <15 mL/min/1.73 m2 for 3 months or the individual is on dialysis.

Clinical noteStage 5 CKD indicates loss of ~85–90% of kidney function; treatment options include dialysis or transplant.

inv-35: eGFR — definition and units

eGFR definitionEstimated glomerular filtration rate (eGFR) is a calculation to estimate kidney filtration, expressed in mL/min/1.73 m2.

Units and interpretationeGFR units = mL/min/1.73 m2; normal adult eGFR is typically ~90–100 mL/min/1.73 m2; eGFR declines with age.

Post-Transplant Coverage
